Can you hook up subs to a factory radio

Subwoofers are routinely added to stock systems to add much needed depth and impact. Subwoofers require amplification, since a stock radio cannot power these devices on their own. Using the right adapter and choosing the best subwoofer and amplifier combination, you can get the factory stereo sounding its best within an afternoon using basic wiring skills. The vast majority of stock radios do not include outputs on the back for wiring amplifiers.

If you want to upgrade your sound system in your car by adding a sub woofer or speakers powered by an auxiliary amplifier without having to get a new head unit then hopefully this should help you: I decided to keep my standard head unit because it looks well in the car, is less likely to attract thieves than a shiny after-market unit and it is a factory upgraded unit anyway and i find it gives pretty good audio quality, it works with the steering wheel controls and has bluetooth and aux-in, so an after-market unit wouldn't offer a substantial upgrade.

Factory head units rarely have RCA or "Low line" outputs which your amplifier will need for it's input signal. Bits You'll need: If you dont have it then you should acquire it from your car manufacturers customer service phone number, your local dealer or the internet. Getting them online can be a bit unreliable and expensive. If you dont have the code and you unplug your stereo it will not allow you to listen to it as it will assume it's been stolen. Don't guess the code as you usually only get a few attempts before it will permanently lock it'self!

Remove your head unit. At the back of your stereo there is most likely one big plug which incorporates all of the inputs and outputs to and from your head unit. Actually, don't mount it yet. Find where you are going to mount it and work out if you need to add any wire to your converter to get it to reach comfortably to where your head unit cables are. Take into account that your head unit will need space behind it to fit back into the dash properly so don't count on splicing into the cables right at the plug with the converter right behind the head unit, it may be better to mount it somewhere else and lengthen the wire to reach.

I initially thought that behind the glove box would be the best place but i ended up cable tying it to a heater pipe that runs down the centre console. When you have a rough idea where you will be mounting your converter unit, solder on the extra wire you'll need to reach your head unit cables and insulate them with electricians tape or heat shrink tubing.

Okay, now you'll need to match up your head unit wiring with the wiring required by your converter. Your converter should come with wiring instructions so you will just need to match up the wires and splice them with the scotch blocks, use the pliers to press the metal splice bar so you can be sure of a good connection.

Okay so now you're converter should be working: Have a cup of tea while you warm up it was -2 Celsius all day when i did this! Tape up your scotch blocks to stop them rattling around and to keep the cables bundled up neatly. Then unplug everything, put it all back in your dash and plug it all back together again If it doesn't work, make sure you have tested the connections with a multimeter and redo any that fail Also, my converter has "Gain adjusters" on the PCB you can adjust with a screwdriver, be sure they aren't turned all the way down, i'm sure they don't go all the way to 0 signal but it's best to be sure: Everythings working, you just need to mount your converter to something, only really to stop it rattling and tapping when you're driving, then cable tie any loose wires together and make sure they won't interfere with things like your glove box lid.

Avoid cable tiying the extension wire to solid things, as it will make removing your head unit difficult in future. Otherwise you can just undo the plug from the converter and then the back of the head unit. Run your RCA wires and remote wire to your Amplifier and then enjoy improved music quality: Hope i have helped, Please comment. Very cool, but one contemplation here.

You are basically parallel-connecting the 4ohm speakers with the Low-Line converter. Assuming that the converter's inputs are 4ohm themselves, that leaves 2ohms of resistance for the stereo system to power to. Not all stereo systems can power to 2ohms without simply burning over the circuits. Have you encountered any issues with your system after doing this? Reply 6 years ago on Introduction. I've had no issues at all, the converter doesn't put a load worth considering on the rear speaker circuits as it's only really "listening" to the signal, it draws all its power separately from a 12v feed.

Very cool, thank you. I have a low-level converter here not that exact brand you're using, but surely they must all behave the same way that I'm going to be installing in my car, but I didn't want to lose the 4 in-car speakers regardless of how weak and pathetic they are in the process. I would expect that they're all based around the same circuitry regardless of brand. As i say its not really influencing the signal to the rear speakers, i doubt it makes any difference you could detect with your ears even at high volume.

Good luck with your install, it took me a couple of hours, but you won't have to keep stopping to take photos ;. S Take two: Thank you: All that stuff plus the amplifier, power capacitor, noise filter and extra speakers will probably take me YEARS: A power cap? I'm thinking that a small-ish power capacitor maybe 0. Reply 5 years ago on Introduction. Do you realize what the power capacitor does in a car stereo system?

It helps the system cope with the spikes in power required to punch the bass, by reducing the load on the alternator and car battery. Reply 3 months ago. The ONLY thing a capacitor does is keep your headlights from dimming every time the bass hits. It does this at the expense of audio quality so unless your headlights are dimming enough to bother you all a cap will do is make your stereo sound worse.

There is a really long thread on this topic over on crutchfield where a couple of electrical engineers explain in much more detail than I can. If you need me to I can dig up the link, if you Google "car audio capacitor" it should be one of the first results. Reply 3 years ago. I need some advice. I keep getting a humming sound from my subwoofer. I have used a speaker 2 rca with auto remote on a 4 guage wire kit. Any ideas on how i could stop this noise?? Reply 1 year ago. Did you run RCA cables and power wire down the same side of the car?

Try running power down one side and RCA the other. Make sure power wire is same gauge as ground off the amp. Reply 2 years ago. HI i have the same with my sub at home. Question 4 months ago on Step 2. Answer 4 months ago. There might be a wiring diagram online for your car. If you have a multimeter or a test light, the Acc circuit will show 0v to ground with the ignition off and 12v to ground with the ignition on.

Hope this helps. There is only front and rear speaker input but the amp also supplies a woofer? If not what would I need to get these two systems working, was also hoping to get the 12 Disk CD changer connected up -- trying to keep the system with original OEM harness as much as possible.. Everything works fine but sometimes i get a loud humming sound from the subwoofer. This happens when i switch the car off or when i open the door.

Any ideas on how i can prevent this from happening?? I have installed a kit like you are talking about, it was 4 or 5 speaker wires that were spliced total. For the REM wire, I recommend wiring it to a fuse in your fuse box to prevent battery drain. Make sure the fuse you choose is only active when the car is on. By g Follow.

Adding RCAs to a Standard Car Head Unit

A sub woofer or two in a vehicle can make the world of difference in listening to music. It is very important to match the RMS of your subs to your amp. You want an amp more powerful than your sub, because you don't want your sub to clip. Clipping is the number one reason of bass distortion. To create this article, 35 people, some anonymous, worked to edit and improve it over time. This article has also been viewed , times.

Installing an amplifier in your car's audio system can seem overwhelming, but installing one without RCA jacks can be downright intimidating. Older systems usually lack RCA jacks, but just because you have an older system does not mean you cannot add an amp for additional power to push your speakers or subwoofers. Before you begin the installation process, it's imperative that you make sure the amp you've chosen is capable of accepting speaker or line-level connections. Once you've double-checked these things, you're ready to start. Determine an ideal location for your amp inside the cabin or trunk of your vehicle. You can mount it on the back of a seat, on the sidewall, on the back of your subwoofer box or on the floor of the trunk away from any loose items that may damage the amp by shifting when the car moves. Open the amp wiring kit, which contains all the wiring you'll need to hook-up your amp. You will need to connect the lengthy, red wire to the positive terminal of the battery. This red power wire should be thicker than your speaker wire--typically 8-gauge works fine.

Wiring up an amplifier to a stock radio is something that many of our customers do themselves.
